BINDER.

SPECIFICATION forming part of Letters Patent No. 767,277, dated. Augus9, 1904.

. of Application filed November 8, 1902. Serial No. 180,599- (No model.)

To all whom, it may concern:

capable of practical service without additional inclosing features.

The invention consists in the construction and arrangement of theseveral parts, which will be more'fully hereinafter described andclaimed.

1n the drawings, Figure 1 is aperspective of a binder embodying thefeatures of the inven-.

tion and showing the manner of practically using the same. Fig. 2 is atop plan view of the improved binder. Fig. 3 is a side elevation of thesame. Figs. 4 and 5 are elevations of opposite ends of the binder.

Similar numerals of reference are employed to indicate correspondingparts in the several news.

Numeral 1 designates a solid back of elongated form and preferablyconstructed from wood or other light material, and for convenience inapplying the same within the hinged portion of a temporary book-binderor backs the improved device is given a convex contour at one sideterminating at the opposite edges of a flat face 2, against which leavesor sheets are brought to bear when the improved device is applied to itsintended use. The opposite ends of the back 1 are preferably coveredwith reinforce-pieces, which consist of fabric or other material whichfit over said ends, as at 3, to give the entire device a neat appearanceand also to shield the said ends and reduce the wear thereof on portionsof the hinged device of a back in which the binder may be placed. On oneof the reinforce-pieces on one end of the back 1 ahinged plate 4 issecured and has an upwardly-projecting knuckle member 5, formed with aslot 6 in its upper free end. The said plate 4 is immovably applied, andin the upper slotted end of the knuckle member one terminal of aclampingbar 7 is pivotally secured and normally extends over the centerof the face 2in a longi tudinal direction. On the oppositereinforcepiece on the other end of the back 1 a hinged plate 8 isimmovably applied and has upper knuckles 9, between which a knuckle 10of an angular catch 11 is movably' held, the said catch beingformed withan inwardly-projecting tongue 12, having an aperture 13 therein. Thefree end of the clamping-bar 7 has an upwardly-projecting stud 14: toengage the aperture 13 in the tongue 12 of the catch.

' The clamping-bar 7 has an elevated central portion 15 and contactdepressions 16 on opposite sides of the center to thus provide twopositive holding or clamping points in the length of the bar which arebrought into close relation to the face 2 when said bar is locked downagainst the face, and to avoid injury to the leaves or sheets engaged bythe said depressions 16 the latter have smooth convex bearing edges.

In use the clamping-bar 7 is released by disengaging the stud 14 thereoffrom the tongue 12 of the catch 11, and when said bar is thus releasedit can be thrown back or drawn away from the face 2 and a sheet, leaf,or other part of a magazine, pamphlet, or other publication to betemporarily bound by the improved device is disposed on or applied tothe face 2, and the clamping bar is then pressed inwardly and caused tofirmly engage the part of the magazine, pamphlet, or other device on theface and secured by the catch 11. The two contact depressions 16 areexceptionally effective in holding the sheet, leaf, or other deviceapplied to the face 2 by reason of the two points of pressure providedthereby in contradistinction to the unreliable single-contact portionsof clamping-bars of many binders now in use which are liable to tear theleaves or sheets engaged thereby. Moreover, the two contact depressions16 are exceptionally efiective in holding thin sheets or leaves. I

The several parts of the deviceof the improved binder are so constructedas to stand considerable strain and resist breakage, and it will beunderstood that the clamping-bar 7 will be sufliciently resilient tocause it to yield when applied over a bulky device disposed on the face2. The hinged catch 11 is also an important feature in the presentconstruction, as it can be gradually brought to bear over the free endof the clamping-bar to engage the stud 14c without liability ofbreakage.

The improved binder will also be found exceptionally useful in holdingnewspapers and can be supplied with any of the usual suspending meansfor this purpose, and to adapt the binder to-general use changes intheproportions and dimensions thereof may be resorted to without departingfrom the spirit of the invention.

Having thus described the invention, what is claimed as new is A bindercomprising a solid back having a continuous unobstructed flat faceprovided on opposite ends with reinforce-pieces, one of which hassecured thereto an upwardlyextended knuckle, the other having a platesecured thereto which also extends above its reinforce-piece and in linewith its knuckle, said plate being provided with an angular catch hingedthereto having an upturned operating-tongue with an aperture therein,and a clamping-bar having a plurality of concavo-convex depressions,said bar having one end hinged to said knuckle and provided on its freeend with a stud for engagement or disengagement with said aperture bymeans of said tongue of said catch, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
